Summary: This patch removes File::SetStream() and File::SetDescriptor(), and replaces most direct uses of File with pointers to File. Instead of calling SetStream() on a file, we make a new file and replace it. My ultimate goal here is to introduce a new API class SBFile, which has full support for python io.IOStream file objects. These can redirect read() and write() to python code, so lldb::Files will need a way to dispatch those methods. Additionally it will need some form of sharing and assigning files, as a SBFile will be passed in and assigned to the main IO streams of the debugger. In my prototype patch queue, I make File itself copyable and add a secondary class FileOps to manage the sharing and dispatch. In that case SBFile was a unique_ptr<File>. (here: https://github.com/smoofra/llvm-project/tree/files) However in review, Pavel Labath suggested that it be shared_ptr instead. (here: https://reviews.llvm.org/D67793) In order for SBFile to use shared_ptr<File>, everything else should as well. If this patch is accepted, I will make SBFile use a shared_ptr I will remove FileOps from future patches and use subclasses of File instead.
